I have not seen mention of. this company:

I emailed for pricing and to see if they have units installed. Even with overproduction on PV I’m back to $50 / mo electric. Not a lot of money but large battery systems are expensive and theV2h makes sense.
I think you'll find that in fact it doesn't make sense, based on the cost of the Setec V2H unit, which is only single phase. It's not clear from the specs, but for 120V output it's likely 20A max, so 2.4 kW max output.
To expand on what LeftieBiker mentioned, you could charge (2) 12V SOK 100 Ah LiFePO4 batteries ($1200 for both), wired in parallel, from the LEAF's DC-DC converter and run a 2000w pure sine inverter ($500) off of the SOK bank, albeit with only 2.4 kWh of capacity. But that should be enough for a buffer battery, so you wouldn't have to hookup the LEAF all that often to transfer energy from the LEAF's pack to the SOK pack unless you were trying to power your entire house
I don't think it would be a good idea to use more than two SOKs in parallel, as that would be too much load on the LEAF's DC-DC converter...
For emergency backup power, 2.4 kWh could last 24 hrs, if you're just powering a fridge and some LED lights. During an extended power outage, if you could drive the LEAF once a day to a location with functional EV charging, you could provide emergency power indefinitely.
